I ARTIFICIAL HAIR.

SPECIFICATION forming part of Letters Patent N0. 729,749, dated June 2, 1903.

Application filed April 12,1902. Serial No: 102,615- (No specimens.)

To all whom, it may concern:

Be it known that I, ROBERT FREEEIoKs, a subject of the King of Prussia, Emperor of Germany, residing at Elberfeld, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Artificial Hair; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the manufacture of artificial hair, and is based upon the wellknown processes for making artificial silk from solutions of cellulose, especially from its copper-oxid ammonia solution. The fiber made in this manner can be advantageously used for a substitute for human hair, if, instead of using, as in the manufacture of artificial silk, an apparatus that produces capillary fiber a suitable apparatus to insure the fiber being of sufficient size and in all respects corresponding to that of human hair.

The foundation substance of this artificial hair is in every respect similar to that used in the manufacture of artificial silk. As the fiber made in this manner has a too brilliant gloss, it is necessary according to circumstances to diminish this. This is accomplished by treating the artificial hair so made withoiland afine-smooth.powder, said powder' being suificiently indifferent in its action on the hair or to its color-as, for instance, talcum powder. The oil must be thin and penetrating or diluted, for instance, with alcohol. The oil must not be a drying oil.

4 In carrying out the invention the cellulose fiber is made of the desired thickness and colored according to the color of the hair that it is'wished to imitate. This coloring-matter may, if desired, be mixed with the cellulose before it is made into fiber, so that in producing the fiber it will be colored throughout. The hair already colored is then, if necessary, graded according to size and spread out and treated with a mixture of oil, such as provence oil, and alcohol. This is sprayed on the hair by means of abellows or other suitable apparatus in such a way that the hair is as evenly covered as possible. The

liquid is advantageously allowed to remain on the hair to somewhat soak in, after which a soft powderfor example, talcum-is blown on it in a similar manner. For light-col0red hair less powder is required; for dark-colored hair, somewhat more. The hair treated in this manner is well worked and combed and then subjected to a heating of about centigrade. By this treatment all the powder is separated from the hair, and in black hair not the least powder will be visible. In this manner artificial hair can be ob tained, the brilliancy of which can be di minished to any required degree to fulfil all the requirements of the various uses to which it may be put.

Having thus described my said invention, what I declare as new therein, and desire to secure by Letters Patent, is-

1. The process for the manufacture of artificial hair, which consists in producing fiber of the required size from solutions of cellulose, coloring said fiber and diminishing the gloss thereof by suitable means, substantially as described.

2. The process for the manufacture of artificial hair, which consists in producing amorphous fiber of the required size from solutions of cellulose, coloring said fiber and diminishing the gloss thereof by treating it with oil and a powder sufficiently indifferent to said hair, substantially as described.

3. The process for the manufacture of artificial hair, which consists in forming amorphous fiber of the required size from solutions of cellulose, coloring the fiber, treating it with an alcoholic solution of an oil and a suitable soft powder, substantially as described.

4. The process for the manufacture of artificial hair, which consists in producing colored fiber of the required thickness from solutions of cellulose, treating the same with an alcoholic solution of an oil and then powdered talcum, substantially as described.

5. The process for the manufacture of artificial hair, which consists in producing colored fiber of the required thickness from solutions of cellulose, treating the same with an alcoholic solution of an oil and then powdered talcum, then heating the hair so treated my invention I have signed my name in presto about 60 oentigrade, substantially as deenoe of two subscribing" witnesses.
